便攜型電容電感測試儀的詳細資料:
便攜型電容電感測試儀是針對變電站現場測量電容器的電容值時存在的問題而專門研制的,它著重解決了以下問題:
(1) 現場測量電(dian)容(rong)器(qi)需(xu)拆除連接線,不僅工作量大而且易(yi)損壞電(dian)容(rong)器(qi);
(2) 電(dian)容表(biao)輸出電(dian)壓低而導(dao)致故障檢(jian)出率低。
該儀器具有(you)測(ce)量(liang)工作量(liang)小(xiao)、快捷簡便、性能穩定(ding)、測(ce)量(liang)準確、故障檢出率高(gao)等特(te)點。
(3) 測量電抗器(qi)電感量。
采用橋式(shi)電(dian)(dian)路結構,標準電(dian)(dian)容(rong)(rong)器(qi)(qi)和(he)被試(shi)電(dian)(dian)容(rong)(rong)器(qi)(qi)作(zuo)為橋式(shi)電(dian)(dian)路的(de)兩臂(bei)。當進行電(dian)(dian)容(rong)(rong)器(qi)(qi)電(dian)(dian)容(rong)(rong)值測量時(shi),測試(shi)電(dian)(dian)壓同時(shi)施加在標準電(dian)(dian)容(rong)(rong)器(qi)(qi)和(he)被試(shi)電(dian)(dian)容(rong)(rong)器(qi)(qi)上(shang),處理(li)器(qi)(qi)通過(guo)傳(chuan)感器(qi)(qi)同采集(ji)流過(guo)兩者的(de)電(dian)(dian)流信(xin)號(hao)并進行處理(li)后得也被試(shi)電(dian)(dian)容(rong)(rong)器(qi)(qi)的(de)電(dian)(dian)容(rong)(rong)值。
由于采用標準電容器(qi)、被試(shi)電容器(qi)同步(bu)采樣技術,可(ke)(ke)不受電源電壓波(bo)動(dong)(dong)的(de)影響;加之測量(liang)過程是全自動(dong)(dong)進行(xing)的(de),避免了手動(dong)(dong)操(cao)作(zuo)引起(qi)的(de)誤差,因此具有穩定性好、重復(fu)性好,準確可(ke)(ke)靠的(de)特(te)點。
